Description
Technical Field
[0001] The utility model belongs to the technical field of toys, and specifically relates to a four-axis aircraft toy. Background Art
[0002] The quadcopter toy includes a fuselage body and four rotor units; each rotor unit includes a rotor and a motor that drives the rotor to rotate. The toy's posture can be adjusted and flight power can be obtained by changing the motor speed of each rotor unit.
[0003] Quadcopter toys have been around for many years. In order to enhance the fun and avoid aesthetic fatigue, merchants always try to give them new functions and new ways of playing. Recently, a quadcopter toy with a circular decorative ring has appeared. The circular decorative ring is fixedly connected to a horizontal shaft, which passes through the fuselage body. The extension direction of the horizontal shaft is the diameter direction of the circular decorative ring. The fuselage body is also provided with a main motor and a transmission mechanism that drives the horizontal shaft and the circular decorative ring to rotate. The fuselage body and the four rotor units are located inside the spherical space surrounded by the rotation trajectory of the circular decorative ring. The circular decorative ring is also provided with an LED light strip. In this way, during the flight, the main motor drives the circular decorative ring surrounding the fuselage body and the four rotor units to rotate rapidly, and the LED light strip of the circular decorative ring emits brilliant colors. The entire quadcopter toy looks like a large standard spherical flying ball, which is novel and interesting and enhances its appeal.
[0004] The power supply of the above-mentioned LED light strip is usually installed on the fixed body. In order to connect the power supply to the rotating circular decorative ring LED light strip, in the prior art, a metal sleeve is generally sleeved on the outside of the horizontal shaft, and then a conductive sleeve is sleeved on the outside of the metal sleeve, or a brush is pressed on the outside of the metal sleeve. However, the structure of the conductive sleeve requires that the inner and outer diameters of the conductive sleeve and the metal sleeve are precisely matched, so the manufacturing is difficult and the cost is high. As for the structural form of the metal sleeve, there are also the following shortcomings: since the quadcopter toy requires the fuselage to be as light as possible, the main motor that drives the circular decorative ring to rotate is generally required to be small in size and weight, that is, the output torque is small, and the brush sheet and the metal sleeve have a certain contact area, that is, there is a considerable friction, which will consume a large proportion of the output torque of the main motor and seriously affect the rotation speed of the circular decorative ring; if you want to reduce the friction between the brush sheet and the metal sleeve, you can only reduce the elasticity or deformation of the brush sheet, but in this way, when the horizontal shaft rotates rapidly and vibrates, it is impossible to ensure that the brush sheet maintains contact with the metal sleeve at every moment, that is, it is easy to have intermittent power failures, which in turn affects the viewing effect; and the brush sheet has the problem of metal fatigue. As the use time increases, the problem of unreliable contact will become more and more serious. In addition, since the quadcopter toy requires the body to be as light as possible, the wall thickness of the metal sleeve is required to be as thin as possible, generally less than 0.1 mm. When welding conductive wires, it is usually difficult to weld the metal wall of this thickness firmly if ordinary welding methods are used. If special laser welding methods are used, the welding cost is relatively high. Utility Model Content
[0005] The utility model aims to overcome the above disadvantages and provide a quadcopter toy, which can ensure that the LED light strip will not be powered off due to loose contact during the high-speed rotation of the circular decorative ring, and the circular decorative ring has low rotation resistance.
[0006] The purpose can be achieved according to the following scheme: a four-axis aircraft toy, including a fuselage body, four rotor units arranged around the fuselage body, each rotor unit includes a rotor, a rotor motor driving the rotor to rotate, and the rotation axis direction of the rotor is vertical; a circular decorative ring is also provided; the circular decorative ring is fixedly connected to a horizontal rotation axis, the horizontal rotation axis passes through the fuselage body, and the extension direction of the horizontal rotation axis is the diameter direction of the circular decorative ring and is horizontal; a main motor and a transmission mechanism driving the horizontal rotation axis and the circular decorative ring to rotate are also provided inside the fuselage body; the fuselage body and the four rotor units are located inside the spherical space surrounded by the rotation trajectory of the circular decorative ring; the circular decorative ring is provided with LE D light strip; the horizontal shaft is also sleeved with a circular metal sleeve, which is divided into two sections, the left and right sections of the circular metal sleeves are respectively located on the left and right opposite sides of the center of the fuselage body, the left and right sections of the circular metal sleeves are fixedly connected to the fuselage body, and the circular metal sleeves and the horizontal shaft can rotate relatively; a light strip circuit board is installed inside the fuselage body, the light strip circuit board is fixedly connected to the fuselage body, and the light strip circuit board is provided with a positive output point and a negative output point; the positive output point of the light strip circuit board is electrically connected to the proximal end of the first section of the circular metal sleeve, and the negative output point of the light strip circuit board is electrically connected to the proximal end of the second section of the circular metal sleeve, characterized in that: A first outer sleeve is also sleeved on the outer side of the distal end of the first section of the circular metal sleeve, and a second outer sleeve is also sleeved on the outer side of the distal end of the second section of the circular metal sleeve. The first outer sleeve, the second outer sleeve and the circular decorative ring are integrally injection-molded and rotate synchronously with the circular decorative ring. The first outer sleeve also forms a first cylindrical protrusion, and a first spring installation cavity is formed inside the first cylindrical protrusion, and a first compression spring is installed in the first spring installation cavity; the second outer sleeve also forms a second cylindrical protrusion, and a second spring installation cavity is formed inside the second cylindrical protrusion, and a second compression spring is installed in the second spring installation cavity. The axial directions of the first compression spring and the axial directions of the second compression spring are perpendicular to the horizontal rotation axis. The first compression spring and the second compression spring rotate synchronously with the circular decorative ring. The first compression spring touches the circumferential surface of the distal end of the first section of the circular metal sleeve, and the second compression spring touches the circumferential surface of the distal end of the second section of the circular metal sleeve. The positive pole of the LED light strip is connected to the first compression spring, and the negative pole of the LED light strip is connected to the second compression spring.
[0007] Preferably, the positive output point and the negative output point are respectively located on the left and right opposite sides of the light strip circuit board; a third compression spring and a fourth compression spring are also provided, and the third compression spring and the fourth compression spring are respectively located on the left and right opposite sides of the main body of the fuselage, and the axial directions of the third compression spring and the fourth compression spring are vertical, the upper end of the third compression spring is fixedly welded to the positive output point of the light strip circuit board, and the lower end of the third compression spring touches the circumferential surface of the proximal end of the first section of the circular metal sleeve, the upper end of the fourth compression spring is fixedly welded to the negative output point of the light strip circuit board, and the lower end of the fourth compression spring touches the circumferential surface of the proximal end of the second section of the circular metal sleeve.
[0008] The so-called proximal end of the circular metal sleeve refers to the end of the circular metal sleeve close to the center of the fuselage body.
[0009] The so-called distal end of the circular metal sleeve refers to the end of the circular metal sleeve that is away from the center of the fuselage body.
[0010] The utility model has the following advantages and effects:
[0011] 1. During use, the first compression spring and the second compression spring rotate around the horizontal axis along with the circular decorative ring. The first compression spring and the second compression spring can be used as components of the LED light strip power supply circuit. Specifically, the power supply is connected from the positive output point of the light strip circuit board to the first section of the circular metal sleeve, the first compression spring, the positive pole of the LED light strip, the LED light strip, the negative pole of the LED light strip, the second compression spring, the second section of the circular metal sleeve, and the negative output point of the light strip circuit board to form a power supply circuit. On the other hand, since the first compression spring and the second compression spring intersect vertically with the corresponding circular metal sleeve, the contact point between the compression spring and the corresponding circular metal sleeve is theoretically only the tangent point between the two, so the contact area is very small, and the size of the contact area is proportional to the friction force, so the friction between the two is small, and the rotation resistance of the circular decorative ring is small, that is, the friction force has little effect on the rotation speed of the circular decorative ring, ensuring the viewing effect. On the other hand, the first compression spring and the second compression spring have sufficient flexibility / elasticity to ensure that the first compression spring / the second compression spring always maintains contact with the corresponding circular metal sleeve surface, ensuring that the LED light strip will not lose power due to loose contact during the high-speed rotation of the circular decorative ring, and that the first compression spring / the second compression spring will not have the problem of close contact with the circular metal sleeve due to metal fatigue.
[0012] 2. Use the third (fourth) compression spring to form an electrical connection between the proximal end of the fixed circular metal sleeve and the positive (negative) output point of the fixed light strip circuit board. This can avoid the use of welding and the problem of difficulty in welding due to the thin wall thickness of the circular metal sleeve. This electrical connection method is low-cost and reliable.
